Hi,  
Sometimes, when an user has no devices allowed (camera and microphone), a white screen is shown instad of the videoconferenc one.  
The only way I was able to recreate this error is in your demo page following the next steps:

1. Remove permission to camera and microphone in openvidu site
2. Access to a demo videoconferencia
3. The white screen appears

In other computer appear the next message INPUT VIDEO DEVICE NOT FOUND.  
Also I have tried in other type of video like google meet and an advice came out for allowing the camera.

¿Could you help me?  
Thank you

Hi,

OpenVidu Call application may have some issues in this case, when the user has no input devices. We are currently looking into it, so please stay tuned for further notice.

Hi @Grecia,

There was a bug in the prejoin page when user has not media devices. Thanks for reporting it.  
Now it is fixed and it will be available on the next release 2.24.0
